Project description:Pod dehiscence is an important agronomic trait. Pod dehiscence would cause huge yield losses before soybean maturity. Although some of soybean pod dehiscence associated genes have been identified, the underlying mechanism of pod dehiscence is still not comprehensively explained. In this study, we have identified differentially expressed genes (DEGs) between shattering-resistant and shattering-susceptible soybean accessions based on transcriptome analyses of 10 soybean accessions. Long non-coding RNAs (lncRNAs) that may be involved in soybean pod dehiscence were also identified, and we constructed co-expression networks between mRNAs and lncRNAs. RNA sequencing results were further verified by real-time PCR. Furthermore, DEGs were screened through analyzing positions of soybean pod dehiscence quantitative trait locus (QTLs) and phenotypes of soybean pod dehiscence for achieving pod-dehiscence candidate genes.

Project description:Pod size varies among soybean cultivars, but the mechanism is largely unknown. We investigated pod size differences between two cultivars. The larger pod of ‘Tachinagaha’ was due to longer cell proliferation activity than in the shorter pod of ‘Iyodaizu’. Pod size of soybean 9 (GmPSS9), a member of the heat shock protein 70 family, was detected in a major QTL (qPSS on Chr. 2) as a candidate gene for determining pod length by QTL and expression QTL analysis. Expression of GmPSS9 in pods was higher in ‘Tachinagaha’ than in ‘Iyodaizu’ and was highest in early pod development. The difference in expression resulted from an indel polymorphism, Tachinagaha-specific-1, which has a 5′-UTR Py-rich stretch motif that boosts transcription. Treatment with an HSP70 inhibitor reduced plant height, pod length, and pod cell number. Our results identify GmPSS9 as a target gene for pod length which regulates cell number during early pod development.

Project description:Purpose: Soybean aphid (Aphis glycines Matsumura; SBA) is major pest of soybean (Glycine max) in the United States of America. One previous study on soybean, soybean-aphid interactions showed that avirulent (biotype 1) and virulent (biotype 2) biotypes can co-occur and potentially interact on resistant and susceptible soybean resulting induced susceptibility. The main objective of this research was to employ RNA sequencing technique to characterize the induced susceptibility effect in which initial feeding by virulent aphids can increase the suitability of avirulent aphids in both susceptible and resistant cultivars. Methods: The data in this submission come from the green house experiment using two genotypes of soybean: susceptible soybean cultivar was LD12-15838R and the resistant cultivar was LD12-15813Ra (with Rag1 gene) and two aphid populations: biotype 1 (avirulent) and biotype 2 (virulent biotype 2). RNA was extracted from the leave samples from resistant and susceptible cultivars treated with no aphids, biotype 2: biotype1 collected at day 1 and no aphids, biotype 2: biotype1 and no aphids: biotype1 at day 11 using PureLink RNA mini kit (Invitrogen, USA). RNA samples were treated with TURBOTM DNase (Invitrogen, USA) to remove any DNA contamination following the manufacturer’s instructions. Assessment of the isolated RNA integrity was performed by 1% agarose gel electrophoresis, and RNA concentration was measured by Nanodrop 2000 (Thermo Fisher Scientific, USA). Three replicates from these treatments in resistant and susceptible cultivars were pooled in equimolar concentration. RNAseq library construction was prepared using Illumina’s TruSeq Stranded mRNA Kit v1 (San Diego, CA). The libraries were quantified by QuBit dsDNA HS Assay (Life Technologies, Carlsbad, CA) and pooled in equimolar concentrations. The libraries were sequenced on an Illumina NextSeq 500 using a NextSeq 500/550 High Output Reagent Cartridge v2 (San Diego, CA) at 75 cycles. Results: A total of 10 RNA libraries were prepared and sequenced with the sequencing depth ranging from 24,779,816 to 29,72,4913. Total reads of 266,535,654 were subjected to FastQC analysis to determine the data quality using various quality metrics such as mean quality scores, per sequence quality scores, per sequence GC content, and sequence length distribution. The phred quality scores per base for all the samples were higher than 30. The GC content ranged from 45 to 46% and followed the normal distribution. After trimming, more than 99% of the reads were retained as the clean and good quality reads. Upon mapping these reads, we obtained high mapping rate ranging from 90.4% to 92.9%. Among the mapped reads, 85.8% to 91.9% reads were uniquely mapped. Conclusions: The objective of this study is to characterize the mechanism of induced susceptibility in soybean via transcriptional response study of soybean in presence of biotype 1 and biotype 2 soybean aphids using RNA-Seq. The data resulted from this study might provide insights into the interactions between soybean and soybean aphids and identify genes, their regulation and enriched pathways that may be associated with resistance or susceptibility to A. glycines.

Project description:Chinese soybean (Glycine max (L.) Merr.) cultivars Rsmv1 and Ssmv1 were used for soybean mosaic virus (SMV) resistance genes screening. The Rsmv1 cultivar was highly-resistant to SMV but the Ssmv1 cultivar was highly-susceptible. We used microarrays to detail the global programme of gene expression underlying SMV inoculation and identified distinct expression genes between Rsmv1 and Ssmv1.

Project description:To identify more targets in soybean, particularly specific targets of Cd-stress-responsive miRNAs, high-throughput degradome sequencing was used. In total, we obtained 8913111 raw reads from the library which was constructed from a mixture of four samples (HX3-CK, HX3-Cd-treatment, ZH24-CK and ZH24-Cd-treatment). After removing the reads without the CAGAG adaptor, 5430126 unique raw-reads were obtained. The unique sequences were aligned to the G. max genome database, and 6516276 reads were mapped to the genome. The mapped reads from the libraries represented 51481 annotated G. max genes.
